avutil/pixelutils: sad_32x32 sse2/avx2 optimizations.
add ff_pixelutils_sad_32x32_sse2, ff_pixelutils_sad_{a,u}_32x32_sse2,
ff_pixelutils_sad_32x32_avx22, ff_pixelutils_sad_{a,u}_32x32_avx2
use perf record/report profiling, get instructions:u for avx2 sad_32x32:
72.05% pixelutils pixelutils [.] block_sad_32x32_c
18.50% pixelutils pixelutils [.] block_sad_16x16_c
4.78% pixelutils pixelutils [.] block_sad_8x8_c
2.69% pixelutils pixelutils [.] block_sad_4x4_c
0.89% pixelutils pixelutils [.] block_sad_2x2_c
0.16% pixelutils pixelutils [.] ff_pixelutils_sad_32x32_avx2
0.16% pixelutils pixelutils [.] ff_pixelutils_sad_u_32x32_avx2
0.12% pixelutils pixelutils [.] ff_pixelutils_sad_a_32x32_avx2
sse2 sad_32x32 instructions:u like:
71.86% pixelutils pixelutils [.] block_sad_32x32_c
